Method for improving functional safety and increasing the availability of electronic closed loop control systems, and electronic closed loop control systems

摘要

The present invention relates to a method for improving functional safety and increasing the availability of an electronic control system, in particular a motor vehicle control system having a hardware component (1) and a software component (3, 4, 5), The hardware component (1) is abstracted by at least one basic software component (20) and / or a runtime environment (2), and two safety concepts implemented are In order to describe further software levels, the first software level (4) has application software control functions, and the second software level (5) specifically protects against control function failures. Designed as functional monitoring (5) of the method, Furthermore, data encryption (9a, 9b, 9c) provided by at least one hardware component (1) and / or data of at least one communication channel (7) of the hardware component (1) are ensured. The data signature to be used is characterized in that it is used in at least one first software component (3). The invention further describes an electronic control system for carrying out the method. [Selection] Figure 1
